HEATINGEDRUM.

SPECIFICATION forming part of Letters Patent No. 705,217, dated July 22, 1902.

Application filed August 31, 1901. Serial No. 74,022. (No model.)

To all whom, it may concern.-

Be it known that 1, CHARLES W. DAVID- soN, a citizen of the United States, residing at Tonti, in the county of Marion and State of Illinois, have invented'c'erta'in new and useful Improvements in Heating-Drums, of

which the following is a full,'clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to combined heat ing stoves and drums; and it consists in the novel arrangement and construction of parts more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure l is a side elevation of the device. Fig. 2 is a rear elevation. Fig. 3 is a vertical section on line 3 3 of Fig. 2, taken through the drum. Fig. 4 is a front elevation of the drum detached, and Fig. 5 is a top plan of the'drum detached with top hood removed.

The object of my invention is to construct a combined heating stove and drum which shall be simple in construction, one developing a maximum amount of efficiency, one utilizing the fuel to the best advantage, and one possessing further and other advantages better apparent from a detailed description of the invention, which is as follows:

Referring to the drawings, 1 represents an ordinary wood-stove mounted on a base 2, having draft ducts or openings 3, the exit-flue of the stove coupling to the forward section 4 of a heating-drum, also resting on the base 2. The section 4 is provided with a series of air-fines 5, opening at the top and bottom, the air reaching said tubes through the ducts 3 of the base, the products of combustion passing around these tubes downward to and through the pipe-sections 6, which latter serve as means of connecting the lower portion of the outersection 4c of the drum to the inner section 4, as seen in section in Fig. 3. The

whatever issues from the drum.

products eventually escape through the series of fines 7, which, together with the chambers 8 8, constitute collectively the rear section 4 of the drum. The air-fines 5 are surmounted by a hood or deflector 9 for deflecting and properly spreading the air-currents throughout the room. By the time the products reach the outer air they have been practically. andwholly consumed and nosmoke I do not, of course, limitmyself to the character of fuel employed; but I preferably use wood, which leaves little or no ash. The arrows in Fig. 3 fully indicate the course of the products of combustion after they have left the stove 1.

Having described my invention, what I claim is- A combined heating stove anddrum comprising a hollow base having air-ducts, a stove and drum mounted on said base, the drum comprising aninner and outersectionythe inner being coupled to the exit-flue of the stove, a series of vertical air-fines open at both ends formed in the inner section of the drum and communicating attheir bottom with the outer air through the ducts of the hollow base, a hood surmounting the series of air-fines, a seriesof fines and upper and lower chambers coupled together andcollectively forming the outer drum-section, the products passing fromthe stove around the air-fines of the inner drum-section, to the bottom of the drum, thence upward through the lower chamber of the drum, the fines, and upper chamber respectively, and finally outinto the atmosphere, substantially as set forth.

In testimony whereof I affix-my signature in presenceof two witnesses.
